Alain-Marie Guynot de Boismenu (27 December 1870 - 5 November 1953) was a French Roman Catholic prelate who served as the Vicar Apostolic of Papua from 1908 until his retirement in 1945; he was a professed member of the Missionaries of the Sacred Heart and the founder of the Handmaids of the Lord.
He studied under the De La Salle Brothers before beginning his religious formation in Belgium where he did his studies for the priesthood.
He served for a brief period as a teacher before being sent in 1897 to Papua New Guinea to aid in the missions there; he also served the ailing apostolic vicar and was soon after made his coadjutor with the right of succession.
His stewardship of the apostolic vicariate saw the number of missions and catechists increase and his tenure also saw the establishment of new schools and a training center for catechists.The beatification process for the late bishop launched in 1984 and he became titled as a Servant of God.
He later became titled as Venerable in 2014 after Pope Francis confirmed he lived a life of heroic virtue.
